I think there is more GPE then KE because, KE are things that are moving, but yeah if you think of all of the cars and trains and plains, they are all moving, but also GPE is something building up energy inside, getting ready to fall. So just think of all of the leafs in the world getting ready to fall, and all of the cliffs in the world just waiting to drop one of its rocks. So yes I do think there is more GPE then KE in the world.
